Hello everyone. I have been planning on building a computer primarily for gaming for quite a while now, mainly in waiting for the 7970/ Sandy Bridge E launch. Case and peripherals excluded, I have around 2200 to spend on this machine. I see that the 3820 is partially locked, so could that lead to bottlenecking with a 7970 crossfire setup? Or in the grand scheme of things, would the benefits of LGA 2011 (quad channel ram, pcie 3.0) be negligible for serious gaming and it be wiser to go with a 2600k build? I have researched this to the best of my ability and find the conclusions either mixed or inconclusive.
Right now almost no games can take advantage of more than 4 cores. Now since one of the major selling points for the Intel® Core™ i7-2600K, i7-2700K i7-3930K and i7-3960X Extreme Edition happens to be the extra cores and hyper-threading which will have minimal value in gaming. Most of the people who understand the enthusiast space believe that the best gaming CPU right now is the Intel Core i5-2500K. In otherwords the differences between the Intel Core i5-2500K and the Intel Core i7s in a gaming environment make almost no difference in real performance.
Thank you for the helpful responses. The route I was planning on taking is waiting for the i7-3820 release on Feb. 13th, which seems to have similar performance when compared to other CPUs for gaming despite not being fully unlocked. This way I would be able to upgrade to Ivy Bridge E when the time came but still have a very powerful computer in the meantime. Would this be an unwise decision when I could just get a 2500k?
unless your gonna throw multiple high end gfx cards at it then the 2011 isnt worth the effort. the only real benefit over the i5 is the pci-e bandwidth. which will enable you to bypass sharing it as long as the motherboard supports multiple x16 pci-e slots.
if your just going for say 2 mid-high end gaming cards then the 2500k will serve you well and wont loose out by very much at all... maybe 1-2 percent. but for way way less money its certainly worth the loss.
